Question

teorema de tales...................​

Answer 1

Resposta:

$\frac{m}{3} = \frac{2}{4}$ multiplica cruzado:

$4m = 6$

$m = \frac{6}{4}$simplifica por 2:

$m = \frac{3}{2} = 1.5$

Answer 2

$\large \boxed{ \begin{array}{l} \dfrac{m}{3} = \dfrac{2}{4} \Longrightarrow \begin{cases} 4m = 3 \times 2 \\ 4m \: = \: 6 \\ m = 6/4 \\ \boxed{ \boxed{m = \underline{1,5}}}\end{cases}\end{array}}$
